摘要
目的:探讨HRCT肺密度的测定与肺功能的相关性。方法:通过对39例确诊慢性阻塞性肺疾病患者进行深吸气后全肺HRCT检查和同期进行的肺功能检查结果进行对照,分析肺密度与肺功能的相关性和肺气肿患者的各肺叶之间的分部的均匀程度。结果:39例患者的平均肺密度与肺功能的检验有显著意义的相关性,P值<0.05;各肺叶之间的肺密度显示为不均匀分布。结论:HRCT局部肺密度测定与肺气肿的诊断指标存在显著相关性;可简单量化性地诊断及进行肺功能分析。中度肺气肿病灶在肺内呈现不均匀分布。
Objective： To discuss the correlation of pulmonary density and pulmonary function in HRCT. Methods： HRCT scans were made for all of the 39 patients with middle degree emphysema at the end inspiration. The pulmonary density were measured based on the HRCT in pulmonary lobes. Results： There are significance difference in the pulmonary density of lodes. The pulmonary density had a good correation with pulmonary fumction, P valure 〈 0.05. Conclusion：The pulmonary density with ROI method is simple and easy to perform in clinical work. The emphysema in lobes are uneven distribution in middle degree emphysema patients.
